Book 29, Question 12
How far apart should seeds and seedlings be planted?
Plants need room for roots to find water and nutrients, and for leaves to catch sunlight.
If they are too crowded, they compete and all end up small. Good spacing also lets air move between leaves, which helps them dry and keeps diseases from spreading. The seed packet tells the right spacing, which depends on how big the plant will be when grown.
